The present invention relates to new and useful improvements in air conditioning means and has for its primary object to provide, inra manner as hereinafter set forth, a device of this character of the unit type comprising novel rmeans for warming and humidifying the air.

Another important object of the invention is to provide an air conditioning apparatus of the aforementioned character embodying a construction which is such that the air will pass or circulate therethrough Without the use of mechanical propulsion means, such as fans or blowers.

Still another very important object of the invention is to provide an air conditioning apparatus of the character described wherein water is utilized as the medium for transmitting heat to the air as said air passes through the device, said water further constituting the source of the moisture which humidies the air.

Other objects of the invention are to provide an air conditioning device of the character set forth which will be comparatively simple in construction, strong, durable, highly eilicient and reliable in use, compact, light in weight, attractive in appearance and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a View in front elevation of an embodiment of the invention.

Figure 2 is a view in side elevation thereof.

Figure 3 is a top plan view.

Figure 4 is a top plan view of the tank with the top removed therefrom.

Figure 5 is a view in vertical section, taken substantially on the line 5-5 of Fig. 1.

Figure 6 is a view in vertical section through the upper portion of the unit.

Figure 7 is a View in irregular vertical section, taken substantially on the line 'I-'I of Fig. 5.

Figure 8 is a horizontal sectional View, taken substantially on the line 8-8 of Fig. 5.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a heat insulated tank I of suitable capacity for the reception of water. The tank I is mounted on suitable casters 2 to facilitate moving the unit. The lower portion of the front of the tank I is (Cl. 21S-38) provided with a grilled air inlet opening 3. The tank I further includes a removable heat insulated top 4 having an opening 5 in its rear portion communicating with said tank.

Mounted vertically in the front portion of the tank I is a plurality of air conduits B which are spaced from each other to permit the entrance of water therebetween. At their lower ends the conduits 6 communicate with the air inlet opening 3. As illustrated to advantage in Fig. 8 of the drawings, the conduits 6 are formed from a single sheet of suitable metal folded upon itself with the folds xed to the front wall I of the tank I, said front wall 'I also constituting the front walls of said conduits. Referring 15 now to Fig. 5 of the drawings, it will be seen that the conduits 6 are closed at their lower ends to the tank I but are open at their upper ends in spaced relation below the top 4 for communication with the upper portion of said tank.

Mounted in the lower portion of the tank I, rearwardly of the conduits 6, is an electric heater 8. Other means may be utilized for heating the water in the tank I. The heater 8 is enclosed in a spaced metallic casing 9 which is open at one end for the reception of Water. Extending upwardly from the other end portion of the tubular casing 9 is a riser I0 which is open at its upper end. The riser I0 is also provided with a discharge opening I I in its lower portion.

The reference numeral I2 designates a suitable filler neck or the like for the tank I. The tank I is further provided with a Water gauge I3.

Mounted in the upper portion of the tank I, rearwardly of the conduits 6, is a baie I4 which prevents the rise of excessive moisture. The reference numeral I5 designates a comparatively wide, at metallic conduit which is removably secured in the opening 5 of the top 4 for receiving the treated air from the tank I. The con 40 duit I5 is provided with a grilled outlet opening I6 in the upper portion of its front. An arcuate deector I'I in the upper portion of the conduit I5 directs the treated air toward the outlet openlng I6. 45

It is thought that the operation of the device will be readily apparent from a consideration of the foregoing. Air enters the conduits 6 at the lower ends thereof through the inlet opening 3, Heat from the electric heater 8 is transmitted to the conduits 6 by the water in the tank I, said water substantially surrounding said conduits on three sides. As the air is heated it rises in the conduits 6 and flows therefrom into the upper portion of the tank I where it is 55 caused to flow toward the rear of said tank in its passage to the conduit I5. During its passage through the upper portion of the tank I, the heated air picks up moisture or vapor rising from the warm Water in said tank and flows upwardly through the conduits I5 and is discharged through the opening I6. Water entering the tubular casing 9 through the open end thereof, is heated by the electric heater 8 and ilows upwardly through the riser I0 and discharges from the upper end thereof, together with any steam or vapor that may be generated.V This water also discharges through the lower opening II in the riser l0. Should the level of the water in the tank I fall below the upper end of the riser IU, all of the water passing .through the casing 9 will be discharged through the lower opening Il, thus preventing interruption of the circulation. If desired, any suitable means may be provided for automatically maintaining the Waterf at a predetermined level in the tank I. Also, a suitable damper or the like may, if desired, be provided in the upper portion of the tank I or in the conduit I5. Still further, a plurality of baiiles I4 may be provided. While a portable or movable unit has been shown, the

invention may be incorporated as a permanent installation. Y

It is believed that the many advantages of an air conditioning apparatus in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of. the invention as claimed.

What is claimed isz- An air conditioning apparatus of the class described comprising a heat insulated tank for the reception of water, a series of conduits mounted vertically in the front portion of the tank, said tank having an air inlet opening in the lower portion of its front communicating with the conduits, said conduits communicating, at their upper ends, withrthe upper portionl of the tank, a vertical conduit having an outlet opening therein communicating with the rear top portion of the tank, and means .for heating the water mounted in the tank rearwardly of the first named conduits.
